This investigation reports the occurrence of bioactive rare actinomycetes from different indigenous natural substrates of Andhra Pradesh. During the course of our investigation on 20 terrestrial soil samples, 5 marine samples and 3 fresh water samples, a total of 92 rare actinomycetes belonging to Micromonospora, Nocardia, Actinomadura and Thermoactinomyces(More)
We isolated a bioactive streptomycete from marine sediment samples collected at Bay of Bengal, India, during our systematic study of marine actinobacteria. The taxonomic studies indicated that the isolate is related to Strepomyces corchorusii. However, it differed in certain aspects, and, hence, was designated as S. corchorusii AUBN1/7. A solvent extraction(More)
The control of surface wettability of indium tin oxide (In2O3-SnO2) coated glass surfaces is studied. We report here the first observation of purely electrochemical generation of super-hydrophilic surfaces at In2O3-SnO2 electrodes in the absence of an ultraviolet illumination source. This is achieved by the application of high anodic potentials for a(More)

Production of cephalosporin C employing a strain, Cephalosporium sp. NCIM 1039 under solid state fermentation was optimized. Different substrates like wheat bran, wheat grains, rice grains, barley and rice bran were studied to optimize the best substrate. Wheat bran showed the highest antibiotic yield. The physical and chemical parameters were optimized.(More)
Sediment samples from Krishna River at Nagayalanka of Andhra Pradesh, India were investigated as a source of actinomycetes to screen for the production of novel bioactive compounds. During our investigation on fresh water actinomycetes from 5 different river sediment samples, a total of 80 actinomycetes were isolated. Out of these 80 isolates, 30 isolates(More)
Pseudomonads are well known for their degradative abilities and play an important role in the environmental cleanup and they are well known for their opportunistic pathogenic properties. The characteristic feature of Pseudomonas aeruginosa is the production of soluble pigments like Pyocyanin, which is an secondary metabolite that is produced in both solid(More)
